Thank you for your suggestions Mr. Kumar, I was able to solve one of the problems by running Firefox in Safe Mode but this TOKEN ERROR still persists. Please see the attached screenshot.

I don't have any idea on how to abolish this particular issue as it comes on &amp;amp; off and is not a permanent error and when one deletes cookies from YAHOO , Refreshes (F5) screen, it works fine but is not ready to give up.

Please let me know if you have any other suggestion.

Moreover, I will try to run a Malware scan in case it may have got one.

Please let me know if you have any other suggestions for me.

Thank u once again!

Try the Firefox Safe Mode to see how it works there. The Safe Mode is a troubleshooting mode, which disables most add-ons.

(If you're not using it, switch to the Default theme.)

You can open the Firefox 4.0+ Safe Mode by holding the Shift key when you use the Firefox desktop or Start menu shortcut.

Or use the Help menu item and click on the Restart with Add-ons Disabled... menu item while Firefox is running.

Don't select anything right now, just use "'Start in Safe Mode"To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shift key) to open it again.If it is good in the Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one.
